WATER-MOTOR.

Specification of Letters Patent. Patented Aug. 13,1918.

Application filed August 21, 1916. Serial No. 116,111.

To all whom it may concern: Be it known that I, ERICK Gr. ANDERSON, a

citizen of the United States, residing at vertically so as to be moved into or out of.

operative position, as desired. Further objects will appear from the detailed description.

In the drawings Figure 1 is a sectional Viewtaken on a plane flush with the top of'the float, looking down,

Fig. 2 is a section on line 2.2 of Fig. 1, Fig. 3 is a section on line 33 of Fig.- 1, and,

Fig. 1 is a fragmentary detail sectional view of the mounting of oneiof the blades.

The numeral 1 designates fa float of approximately rectangular shape which: may be of any suitable construction. This float comprises a frame formed of a plurality of Near each end of the well 5, at each side spaced rectangular frames 2 secured together and braced by the bracing beams 3. The frame thus constructed is provided with a covering 1 of boards or othersuitable material so as to provide a relatively large air chamber extending throughout the float. The sides 1 0f the float project downward a considerable distance beyond the end i ortions 1 which are raised to form an en inlet opening 1 and an outlet opening 1 at the ends of the float. As will be noted, these openings converge inwardly to the ends of the central rectangular opening or well 5 extending through the float from the top to the bottom thereof. In operation the .float is mounted so that the current flows from the inlet end toward the outlet end. In this position the opening 1 permits the easy entry of a relatively large amount of water which, after operating upon the blades of the motor, to be later described, escapes through the outlet 1.

thereof, is secured a post or standard 6, the standards at each end being in horizontal alinement. Each pair of standards supports, near the upper ends thereof, a rotatably mounted transverse shaft 7. A pulley 8 is keyed on one end of this shaft and is operatively connected by a cord 9 to a similar pulley 1O keyed on a stub shaft 11 rotatably mounted on one of the'standards 6 on the outer end of which is keyed a hand wheel 12. A pinion 13 is keyed on the shaft 7 near each end thereof, adjacent the support 6. By rotating the hand wheel 12, the pinions 13 may be rotated in eitherv direction desired.

The pinions 13 mesh with rack bars 11 which are secured at the ends of an approximately' V-shaped frame 15 mounted within the well 5.

'Therack bars are held securely in spaced relation by brace rods 11 secured to the bars near their upper ends and extending longitudinally of the frame 15.

This frame is composed of spaced horizontal top bars 16, central downwardly proj ecting bars 17 secured at, their upper ends in the bars 16, and lower upwardly and out wardly inclined brace rods 18 secured at their lower ends to the bars 17 and at their upper ends to the outer ends of the top bars 16. This provides a relatively light and very strong and rigid structure. The

.outer ends of the brace rods 18 and the top bars 16 are'also firmly secured in the rack bars 11, near the lower ends thereof. Each rack bar is provided, near its lowerend, with a bearing sleeve 19 rigidly, secured thereto. These sleevesrotatably support a transverse shaft20 at each end of the frame, and a similar shaft 21 is mounted. in the downwardly extending bars 17 in a plane below the plane containing the axes of the shafts 20. It will be evident that, by rotating the hand wheels 12, the frame may be adjusted vertically as desired.

A sprocket wheel 22 is keyed on each shaft 20, near each end thereof. A similar pair of sprocket wheels 23 is keyed on the shaft 21. These wheels are in the same ver through an eye .26 formed integral with and at the approximate center of, a vane or blade 27. The outer end of this blade is provided with an integral eye 28 whlch receives an eye 29 at the upper end of anin- I,

clined brace rod 30, the lower end of which is pivotally secured, as at 31, to the inner "face'of one of the links of the chain 24:.

The blades 27 are mounted at right angles to the chains and are normally maintained in this position bythe brace rods 30. When the chain passes about onset the sprocket wheel'sthe distance.between the rod 25 and the pivotal point 31 will be slightly decreased so that the blade ,will rock about the rod, The pivotal mounting of the blade and the brace rod, and the loose connection betweenthe outer end of the brace rod and .the upper endof the. blade, permit this rocking movementduring the'travel of a blade about.

one of .the sprocket wheels, while normally holding the blade at right angles to the chains, as above stated.

1 ue to the fact that the sprocket wheels 23 are somewhat lower than the sprocket wheels 22, the blades, during the first :half of .the lower part of their travel, will travel downward at an inclination so that they will be presented to thewater at a downward and ,Oufiw ard slant. Due to this slant or inclinaion of the blades, the water obtains a firm grip upon the same so as to move them in the direction of flow of the operating fluid. During the latter half of their lower travel, theblades are at an upward and inward inclination, so that the water exerts a lifting keyed on the outer end thereof.

formed by thechains2e, operation of the motor may be controlled at will.

One of the end shafts 20 of the chain carrying frame isextended and a pully 32 This pulley is in alinement with an opening 33 through the top of the float l. By this means the motor may be connected by a belt,

or.the-.like to the machinery which it is desired to operate therefrom.

It will be evident .that certain changes can bemade in the. construction and arrange- :ment of the d fferent parts of my invention without departing from the field and scope of the same, and I intendto include all such variations, as fall within the scope of the appended claim, inthis application, in which a preferred. form only of .my invention is disclosed.

. What I claim, is

Ina water motor, a frame, pairs of spaced sprocket wheels rotatably mounted at the centerand eachend of the frame in triangular arrangement, the sprocket wheels at the center being in plane lower than those at the ends {of the frame, a pair of chains passed aboutthe sprocket wheels, a plurality of blades rockably mounted at their centers between the chains and disposed at right angles thereto, each of said blades being, providedat its center with an integral eyeegrtendillg the full-length thereof, a rod inserted through said eye and secured between the chainsso as to rockably support. theblade and brace rods pivotally secured at their lower ends to the outer end of said blades and pivotally secured at their inner ends to said chains said rodsacting to hold.

the blades atright angles tothe chains, and permitting rocking novement thereof when passing about a sprocket wheel.

Infestimony whereofl alfix my signature in,presence of two witnesses.
